44/**
45 * Provides access to information about the telephony services on
46 * the device. Applications can use the methods in this class to
47 * determine telephony services and states, as well as to access some
48 * types of subscriber information. Applications can also register
49 * a listener to receive notification of telephony state changes.
50 * <p>
51 * You do not instantiate this class directly; instead, you retrieve
52 * a reference to an instance through
53 * {@link android.content.Context#getSystemService
54 * Context.getSystemService(Context.TELEPHONY_SERVICE)}.
55 * <p>
56 * Note that access to some telephony information is
57 * permission-protected. Your application cannot access the protected
58 * information unless it has the appropriate permissions declared in
59 * its manifest file. Where permissions apply, they are noted in the
60 * the methods through which you access the protected information.
